Proposed ICD–10–CM Surveillance Case Definitions for Injury Hospitalizations and Emergency Department Visits


National Health Statistics Reports, Number 100, January 23, 2017.


This report describes a collaboration between the National Center for Health Statistics and the National Center for Injury Prevention and Control to develop proposed surveillance case definitions for injury hospitalizations and emergency department (ED) visits for use with administrative data sets coded using the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD–10–CM). The proposed ICD–10–CM surveillance case definitions were developed by applying General Equivalence Mappings to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD–9–CM) definitions. As with the ICD–9–CM definitions, there are slight differences between the proposed ICD–10–CM surveillance case definition for injury hospitalizations and the one for ED visits. The inclusion criteria for an injury hospitalization requires a case to have a principal diagnosis of one of the included nature-of-injury (injury diagnosis) codes. The inclusion criteria for an injury ED visit requires the case to have either a principal diagnosis of one of the included nature-of-injury codes or the presence of selected external-cause codes. The ICD–10–CM nature-of-injury and external-cause codes included in the proposed definitions are presented and caveats for use of the proposed definitions are described.
